        {
            string ConId = Context.ConnectionId.ToString();
            // call the clients connected to the hub
            Clients.Group(group).clientmethod(name, ConId, msg);
        }
  ```
* 3.Modify chat page:

  ```
                //Get query string
                function queryString(Key)
                {
                    var url = window.location.href;
                    KeysValues = url.split(/[\?&]+/);
                    for(i = 0; i < KeysValues.length; i++)
                    {
                        KeysValue = KeysValues[i].split("=");
                        if (KeysValue[0] == Key)
                        {
                            return KeysValue[1];
                        }
                    }
                }

                    $(document).ready(function () {

                    //Get name from query string
                    var n = queryString("n");

                    $("#name").html(n);

                    //Get group from query string
                    var g = queryString("g");
  ```
